Google App Engine 端点版本迁移 V1 到 V2

Question

我们使用 android studio 创建了 Google Endpoint api v1。 我们收到了来自谷歌云的电子邮件，其中谷歌 API 版本 v1 已被弃用。所以我们尝试将 v1 更新到 v2。 因此参考以下链接进行迁移。 https://cloud.google.com/endpoints/docs/frameworks/legacy/v1/java/migrating-android#before_you_begin

更改后，当我们尝试运行时显示“.../backend/build/exploded-app”不存在

如果我查看项目中的目录树 我可以根据模块名称“backend”和包含 Discovery 文档的“endpointsDiscoveryDocs”看到展开的目录“../build/exploded-backend”。

“.../backend/build/exploded-app”和“.../backend/build/endpointsClientLibs”不可用

当我尝试执行时，构建成功但显示在 运行后端出错：无法启动进程，工作目录 '...\MyAppliaiton\backend\build\exploded-app' 不存在

我的android项目中使用了以下build.xml

MyApplication build.gradle

buildscript {
    repositories {
        jcenter()
    }
    dependencies {

        classpath 'com.google.guava:guava:19.0'
        classpath 'com.android.tools.build:gradle:2.3.3'
    }
}

allprojects {
    repositories {
        jcenter()
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

应用构建.gradle

**apply plugin: 'com.android.application'

我需要帮助这里发生的事情。

Answer 1

我正在将我的 appengine 模块从 Java 7 更新到 Java 8，并将 Endpoints v1 更新到 Endpoints v2，这真的很麻烦。

我已经解决了

[后端模块]/[后端模块].iml

换行

value="C:\workspace\ [项目] \ [后端模块] \build\exploded-app

到

value="C:\workspace\ [项目] \ [后端模块] \build\exploded-[后端模块]
